I have an arduino with a maker shield on top and a lcd on the breadboard on the maker shield. When I plug in the 9v power jack it makes smoke and something buzzs!


Center of your 9v plug is positive?

You haven't really given any details to help.

Look around your circuit for the part that is burned up.
